Internal components and PCBs are at mains potential when the HRVS-
DN is connected to mains. This voltage is extremely dangerous and
contact with it will cause death or severe injury.
When the HRVS-DN is connected to mains full voltage may appear on
the HRVS-DN’s output terminals and motor’s terminals, even if control
voltage is disconnected and motor is stopped.
The HRVS-DN must be grounded to ensure correct operation, safety and
to prevent damage.
Check that power factor capacitors are not connected to the output side
of the HRVS-DN (U, V, W).
Also make sure that power factor capacitors are not connected to the
bypass preparation bus bars (L1B, L2B, L3B when exist)
The company reserves the right to make any improvements or modifications to its products without

3. INTRODUCTION
3.1 Why Solcon? Why Soft Starters?
9 • Introduction
Three-phase AC induction motors are commonly used in a wide variety of drive applications. Due to their
starting characteristics, in many cases these motors cannot be connected directly to the power supply system.
When starting Direct On Line (DOL) the motor can see a very high surge current reaching up to 6 times (and
more…) the rated motor current. This excessive current puts stress on the supply system and the switchgear.
Also, when starting DOL, a very high peak torque can occur, stressing the driven motor and the mechanical
system including auxiliary power transmission parts (V-belt, gears, etc.).
There are several methods for reducing the damaging effects of this excessive starting current. Conventional
methods include reactors and autotransformers. But these methods only allow the voltage to be reduced in
steps whereas a soft starter provides step-free acceleration of the drive system by continuously increasing the
voltage over a selected period of time. This approach to starting minimizes the effect of high inrush current on
the supply system, the motor and the driven load.
Soft starters provide the following benefits:
• Reduced starting current, eliminates voltage drops and dips of the supply network
• Smoother acceleration of loads, eliminates process or product damage
• Extended lifetime of all mechanical components, e.g. eliminates gearbox damage and results in less
maintenance & downtime
• Extended motor life
• Reduced maintenance and operating costs
The HRVS-DN soft starter represents a logical extension of the Solcon soft starter product range into medium
voltage applications.
With HRVS-DN, Solcon presents an innovative standard product that provides a flexible, low cost alternative
to fixed speed (DOL) starting.
Designed for use with standard medium voltage three-phase squirrel cage induction motors as well as
synchronous motors, this high-performance digital soft starter ensures smooth acceleration and deceleration.
HRVS-DN is available in all standard internationally recognized medium voltage ratings: 2.3kV, 3.3kV, 4.16kV,
6kV and 6.6kV, 10kV, 11kV, 13.2kV, 13.8kV and 15kV.
The standard current output range capability is from 200kW to 27MW.
HRVS-DN is designed and built to meet international standards including:
• IEC • EN • DIN VDE • NEMA • UL/CUL • IEEE
The HRVS-DN soft starters are manufactured at the highest quality level. The entire design, production and
delivery process, (i.e. construction, manufacturing, order processing and logistics delivery center) have been
certified DIN ISO 9001.2000.
The enclosed versions of the HRVS-DN are provided as ready-to-connect cabinet enclosed type units
(example shown in Figure 1) or - for OEM only - chassis type OEM kits (example shown in Figure 2) are
available for building into custom enclosures or other relevant equipment (note: the complete interface
engineering is the responsibility of the user).

3.2 How Soft Starters Work?
Figure 2- HRVS-DN Chassis Type (IP00)
By using thyristors (SCRs) in a phase angle control mode, reduced voltage control can be achieved. Phase
control makes it possible to gradually increase the motor terminal voltage from an initial set point up to the
system supply voltage level. The related starting current and the starting torque can be optimally adjusted to
the motor/load conditions.

Starter (Bypass Preparations not Shown)
Figure 4 - Phase Control of the Line Voltage Using
Semiconductor (SCR) Elements
Figure 5 shows a principal voltage increase curve. Figure 6 demonstrates the torque reduction compared to the
DOL torque. Figure 7 demonstrates typical behavior of motor current.
Figure 5 – Voltage Increase Figure 6 – Torque Reduction Figure 7 – Current Limit
In addition, the Solcon HRVS-DN soft starters provide the "soft stopping" function as a standard feature.
Similar to the reduced voltage start, a stop command gradually reduces the motor voltage over time until the
motor stops. Abrupt stopping is avoided, a specific advantage in pumping applications to prevent the
damaging effects of water hammer and on conveyor belts where the load may be damaged by an abrupt stop.

Figure 8 – HRVS-DN IP00 Unit (OEM Kit)
The IP00 unit (OEM kit) is available for building into custom enclosures or other relevant equipment.
It consists of the following (refer to Figure 8 above):
• Power Section consists of the 3 identical phase stacks, firing PCBs, power supplies to the firing PCBs
(in HRVS-DN from 10kV and up power supplies to the firing PCBs are separated from the Power
Section), 3 CTs and the connection harness to the low voltage compartment (including copper wires
and fiber optic wires). The Power Section is installed in the medium voltage compartment of the
cabinet.
• Control Module is the “brain” of the soft starter. It consists of the main CPU PCB, fireboard PCB,
power supply, optional PCBs (when ordered) and input/output interface terminals.
The Control Module for HRVS-DN is identical for all ratings and suitable for mounting in the L.V.
compartment of the cabinet which should be fully segregated from the M.V. compartment.
Interposing relays should be connected to all HRVS-DN auxiliary contacts, three relays must be
incorporated: Immediate, End of Acceleration and Fault.
• Firing Transformer. This transformer is applicable for 115VAC or 230VAC control voltages.
For HRVS-DN controlled by DC control voltages - DC power supply is supplied – for details consult the
factory.
The Firing transformer is installed in the low voltage compartment of the cabinet and supplies control
power to the firing PCBs located in the Power Section of the HRVS-DN in the medium voltage
compartment of the cabinet.
• EPT-Tx (transmitter) and EPT-Rx (receiver) are used instead of the traditional voltage transformer to
measure the input voltage.
The EPT-Tx is installed in the medium voltage compartment and is connected to the mains bus bars
downstream from the Line Contactor.
The EPT-Rx is installed in the low voltage compartment of the cabinet.
The EPT-Tx and EPT-Rx are connected by 2 fiber optic wires which are part of the connection
harness.

Description
Sets motor’s INITIAL STARTING VOLTAGE.
The motor’s torque is directly proportional to the square of the
voltage.
This adjustment also determines the inrush current and
mechanical shock. A setting that is too high may cause high
initial mechanical shock and high inrush current. This can
occur even if CURRENT LIMIT is set low because the INITIAL
VOLTAGE setting overrides the CURRENT LIMIT setting.
A setting that is too low may result in prolonged time until the
motor starts to turn. In general, this setting should ensure that
the motor starts turning immediately after start signal.

The range of the

Note:
When INITIAL VOLTAGE is set its maximum value, this
displays changes to INITIAL CURRENT.
When INITIAL CURRENT is set the HRVS-DN causes current
ramp instead of voltage ramp.
Sets motor’s CURRENT LIMIT during starting.
A setting that is too high will increase the current drawn from
mains and faster acceleration.
A setting that is too low may prevent the motor from
completing acceleration process and reaching full speed. In
general, this setting should be set to a value that is high
enough to prevent stalling.
Note:
CURRENT LIMIT does not operate during RUN and SOFT
STOP.

Notes:
• Since CURRENT LIMIT overrides ACC. TIME, when
CURRENT LIMIT is set low, the starting time will be longer
than the ACC. TIME setting.
• When the motor reaches full speed before voltage reaches
nominal, ACC. TIME setting is overridden, causing voltage
to quickly ramp-up to nominal.
• Using starting curves 2, 3, 4 prevents quick ramp up.
Sets MAXIMUM START TIME.
The maximum allowable start time, from the start signal to the

For example, this can occur when the CURRENT LIMIT

7.8.3.1 Soft Start Parameters
The HRVS-DN incorporates five starting curves to enable you to select a suitable torque curve.
SOFT START CURVE 1 – Standard curve (Default). This curve is the most suitable curve for preventing
prolonged starting and motor overheating.
SOFT START CURVE 2-4 - Pump Control - Induction motors produce peak torque of up to 3 times the rated
torque towards the end of starting process. In some pump applications, this peak may cause pressure surge in
the pipes.
SOFT START CURVE 2, 3, 4 – During acceleration, before reaching peak torque, the Pump Control Program
automatically controls the voltage ramp-up, thus, reducing peak torque.
Choice of four pump control acceleration curves: 1!, 2!, 3!, 4!
SOFT START CURVE 5 (TORQUE) – Torque Controlled acceleration - This provides a smooth timecontrolled
torque ramp for the motor and the pump.
Note:
Always start with SOFT START CURVE 1. If towards the end of acceleration peak torque is too high (pressure
is too high) proceed to Curve 2, 3, 4 or 5 in that order.
SOFT START CURVE 0 – Basic curve. This curve uses less feedback signals. Use this curve if other curves
do not give good results.
WARNING!
When operating in SOFT START CURVE 0 motor must be loaded, otherwise,
vibration may occur towards the end of the soft start process.

The parameter TURN BYPAS ON AT determines motor current below which the soft starter goes into Run
condition and closes the End Of Acceleration relay.
The parameter MIN TIME TO BYPS assures that Run condition can not be reached before the set time after
the beginning of the starting process.
This special feature is for synchronous motor starting applications where the motor current at asynchronous
speed may be at higher level than regular asynchronous motor starting conditions.
In this case the level of current at which the Run condition is being achieved can be programmed.

Determines the motor’s voltage ramp down time.
Note:
The HRVS-DN operates with a Bypass Contactor. The Bypass
Contactor is controlled by the HRVS-DN’s End of Acceleration
relay. Upon soft stop initiation the End of Acceleration relay is
de-energized, the load is transferred to the HRVS-DN, and
voltage begins ramping down.

7.8.4.1 Soft Stop Parameters
67 • Control Keypad
SOFT STOP initiation opens the End of Acceleration contact and opens the Bypass Contactor. Load will be
transferred to the HRVS-DN thyristors and voltage begins to ramp down.
The HRVS-DN incorporates 5 stopping curves that enable you to select the suitable torque curve:
SOFT STOP CURVE 1 – Standard Curve (Default) – voltage is linearly reduced from nominal to zero.
The most stable and suitable curve for preventing prolonged stopping and motor overheating.
SOFT STOP CURVE 2, 3, 4 Pump Control – In some pump applications, when pumping to higher elevation a
considerable part of the torque is constant and does not decrease with speed.
It may happen that during the deceleration process when voltage decreases the motor torque abruptly falls
below load torque (instead of smoothly decreasing speed to zero), thus closing the valve and causing water
hammer.
Curves 2, 3 and 4 eliminate the water hammer phenomenon. In pump applications the load torque decreases
in square relation to the speed, thus correcting control of voltage to reduce torque adequately and to smooth
deceleration to a stop.
Note:
It is recommended that SOFT STOP CURVE 1 be used for all standard applications (not pumps).
To reduce water hammer, select SOFT STOP CURVE 2, then 3, then 4 in that order.
SOST STOP CURVE 5 - Torque Curve - Provides linear deceleration of the torque. In certain loads, linear
torque deceleration can result in close to linear speed deceleration, thus eliminating stall conditions.
Note:
Always use SOFT STOP CURVE 1. If the motor stalls quickly instead of slowly decreasing its speed, select
SOFT STOP CURVE 2, 3, 4 or 5 in that order until the problem is solved.
SOFT STOP CURVE 0 – Basic curve. This curve uses less feedback signals. Use this curve if other curves do
not give good results.
WARNING!
When operating in SOFT STOP CURVE 0 motor must be loaded, otherwise,
vibration may occur during the beginning of the soft stop process.

8. MOTOR AND SOFT STARTER PROTECTION
75 • Motor and Soft Starter Protection
Protection functions are distinguished between adjustable protection functions and non-adjustable protection
functions.
Upon fault – motor stops, Fault LED lights and Fault Relay chances position.
The LCD shows TRIP: < fault description>. (for example: TRIP: UNDER CURRENT).
WARNING!
Upon any fault read carefully the COMMISSIONING AND OPERATION
chapters in this manual before you try to identify the cause.
8.1 Adjustable Protection Functions
8.1.1 UNDER CURRENT
Trips the HRVS-DN when line current drops below the preset level for the preset time.
Check UNDERCURR. TRIP and UNDERCURR. DELAY settings; check line currents through L1, L2, L3.
For protection parameter settings refer to section 7.8.2 page 55.
8.1.2 O/C –SHEAR PIN
Trips the HRVS-DN when:
• Instantaneously when current exceeds 850% of HRVS-DN FLC
• While starting when current exceeds 850% of Motor FLA
• While running when current exceeds 100-850% of Motor FLA with a programmable delay of 0-5 seconds.
Delay is overridden when current reaches 850% of HRVS-DN FLC.
Check that the motor is not stalled or jammed.
Check FLA, FLC settings.
Check motor and cable connections.
Perform a “Megger” test to check the condition of the motor and cables.
For protection parameter settings refer to section 7.8.2 page 55.
8.1.3 OVERLOAD
Trips the HRVS-DN when current exceeds the OVERLOAD TRIP level and the thermal register has filled up.
Check FLA, FLC and overload settings and check motor current, then wait at least 15 minutes to let the motor
and HRVS-DN cool down before restarting.
You may want to check motor THERMAL CAPACITY as displayed in the data page refer to section 7.8.1
page 54.
For protection parameter settings refer to section 7.8.2 page 55.
8.1.4 UNBALANCE CURRENT
Current Unbalance is the difference between the maximum and minimum values of the motor’s three line
currents divided by the motor’s maximum current or motor FLA, whichever is greater. A fault occurs when the
actual Unbalance is greater than the setpoint for a delay that exceeds the UNBALANCE DELAY.
For protection parameter settings refer to section 7.8.2 page 55.
8.1.5 GROUND FAULT
Trips the motor when Ground Current exceeds the preset GND FAULT TRIP for more than
GND FAULT DLY.

For protection parameter settings refer to section 7.8.2 page 55.
8.1.7 OVER VOLTAGE
Trips the HRVS-DN when line voltage increases above the preset level for the preset time.
Check OVERVOLT. TRIP and OVERVOLT. DELAY settings, check line voltages on L1, L2, L3.
For protection parameter settings refer to section 7.8.2 page 55.
8.1.8 LONG START TIME
Trips the HRVS-DN if output voltage does not reach nominal at the preset MAX. START TIME.
Check FLA, FLC and MAX. START TIME settings. Increase INITIAL VOLTAGE, CURRENT LIMIT & MAX.
START TIME or decrease ACC. TIME as necessary.
For parameter settings refer to section 7.8.3 page 60.
8.1.9 OPEN BYPASS
Operates when the Bypass Contactor does not close after the EOA contact of the HRVS-DN closes.
Note: This protection can be disabled by setting BY PASS OPEN TRIP to DISABLE when the Bypass is
connected in a separate cabinet, in a configuration where the starter CTs do not measure motor current while
the Bypass Contactor is closed.
For parameter settings refer to section 7.8.6 page 69.
8.1.10 SET CURVE TO 0
Trip occurs if the Soft Starter starts with a non-adequate starting curve to the network.
Change start and stop parameter to SOFT START CURVE 0 and try again.
For parameter settings refer to section 7.8.3 page 60.
8.1.11 PWR ON & NO STRT
Operates upon main voltage connection and activated while mains voltage is connected to the HRVS-DN for
more than 30 seconds without a start signal.
Note: This protection can be disabled by setting PWR ON & NO STRT to DISABLE. Do not set to DISABLE
before you consult the factory!
Reset the fault, and initiate the start command within less than 30 seconds after mains voltage is applied to
L1, L2 and L3.
8.1.12 MOTOR INSULATION
(Optional) Trips the HRVS-DN when the motor insulation level decreases below the trip level set.
Check motor and cable insulation level.
For INSULATION ALARM/TRIP protection settings refer to section 7.8.6 page 69.
8.1.13 PHASE SEQUENCE
Trips the HRVS-DN if line phase sequence is wrong.
The HRVS-DN can be operated in any phase sequence as set in the PHASE SEQUENCE protection of the
soft starter.
_____________________________________________________________________________________________

77 • Motor and Soft Starter Protection
It allows the motor to start in the POSITIVE sequence of the mains OR in the NEGATIVE sequence of the
mains or, when set to IGNORE both sequences.
For PHASE SEQUANCE protection settings refer to section 7.8.6 page 69.
8.1.14 TOO MANY STARTS
Trips the HRVS-DN if NUMBER OF STARTS during START PERIOD exceeds the preset number.
You must wait until the motor and the starter cool down according to the START INHIBIT setting.
For protection settings refer to section 7.8.3 page 60.
8.2 Non Adjustable Protection Functions
8.2.1 UNDER/OVER FREQUENCY
Trips the HRVS-DN if frequency is not in the range of 44-65Hz
Check that frequency variations are between 44-65Hz.
8.2.2 PHASE LOSS
Trips the starter if 1 or 2 phases are missing.
Check lines voltages and correct connection.
8.2.3 WRONG PARAMETERS
After power up parameters not transferred from RAM to EEPROM or vice versa.
Press Reset then load DEFAULT PARAMETERS. Refer to section 7.6.3 page 49 for more details on loading
default parameters.Note that obtaining DEFAULT PARAMETERS erases all previously modified settings and
requires the operator to reprogram all parameters that differ from the factory default.
Note:
It is especially important to reprogram the RATED LINE VOLTAGE and STARTER FLC (as shown on the
label of the HRVS-DN) and all other parameters in the MAIN & PROTECT mod page. Refer to section 7.8.2
page 55.
8.2.4 STORAGE ERROR
When trying to store parameters at the end of a mode page or after lading DEFAULT PRAMETERS.
Press Reset and try again. If this does not succeed load DEFAULT PARAMETERS. Refer to section 7.6.3
page 49 for more details on loading default parameters.
Note that obtaining DEFAULT PARAMETERS erases all previously modified settings and requires the
operator to reprogram all parameters that differ from the factory default.
Note: It is especially important to reprogram the RATED LINE VOLTAGE and STARTER FLC (as shown on
the label of the HRVS-DN) and all other parameters in MAIN & PROTECT mod page. Refer to section 7.8.2
page 55.
8.2.5 S. SCR OR WR. CON
Operational after start signal. Trips if the motor is not properly connected to HRVS-DN’s load terminals, when:
• Internal disconnection is detected in the motor winding
• One or more of the SCRs have been shorted.
• Incorrect fiber optic leads connection
This protection is not active when SOFT START CURVE 0 is selected.
Check with an ohmmeter between L1-U, L2-V, L3-W; resistances are listed on section 14.1 page 116.
Check for no voltage on terminals U, V, W (from parallel system or an independent bypass).
SCRs may fail due to:
• High short current not protected by proper fuses.
• High voltage spikes not protected by proper external Varistors.
• Frequent starting at maximum conditions or fault conditions.
For SOFT START CURVE 0 setting refer to section 7.8.2 page 55.
_______________________________________________________________________________________________

78 • Motor and Soft Starter Protection
8.2.6 OVER TEMPERATURE
Thermal sensors are mounted on the heat-sinks of the Power Section and trip the HRVS-DN when the
temperature rises above 85ºC.
WARNING!
The over temperature protection is designed to operate under normal
conditions, e.g., in the event of extended low overload, insufficient ventilation
due to fan stoppage or air flow blockage.
Incorrect HRVS-DN selection, frequent starting at max. conditions, or repeated
starting under fault conditions can cause the SCR to overheat and fail before
the heat-sink reaches 85°C thereby causing the thermal sensors to trip the
HRVS-DN.
8.2.7 EXTERNAL FAULT 1 & EXTERNAL FAULT 2
External Faults becomes operational when HRVS-DN is energized.
The HRVS-DN will trip if contact between terminals 19 and 21 closes for more than 2 sec.
8.3 Fault and Reset
When any of the above protections trip (except INSULATION ALARM), the HRVS-DN locks in a fault condition
thus disabling firing of the thyristors. Fault LED lights, fault description is displayed on the LCD and the fault
relay operates.
• For local reset, after fault has been removed, press Reset key.
• Remote reset can be performed through terminals 7 or 8 (see I/O PROGRAMMING section 7.8.7
page 71).
When a fault occurs, followed by a voltage outage, the fault condition is latched and reappears upon voltage
restoration.
Note:
Reset (Local, Remote, Serial Link or Auto Reset) is not possible as long as the START signal exists, except
for UNDER CURRENT trip.
8.4 Auto Reset

with installation, operation or maintenance.
Should further information be desired or should particular problems arise which
are not covered sufficiently for the purchaser's purposes, please contact your local
Solcon office.
Further, the contents of this Manual shall neither become a part of nor modify any
prior or existing agreement, commitment or relationship. The sales contract
contains the entire obligation of Solcon. The warranty contained in the contract
between the parties is the sole warranty of Solcon. Any statements contained
herein do not create new warranties nor modify the existing warranty.
• Read this manual carefully before operating the equipment and follow its
instructions.
• Installation, operation and maintenance should be in strict accordance with
this manual, national codes and good practice. Installation or operation not
performed in strict accordance with these instructions will avoid
manufacturer’s warranty.
• Never open the medium voltage doors of the cabinet while medium
voltage is connected to the cabinet.
• Do not open the medium voltage doors, even if the motor is not running
and the Line Contactor is open. Medium voltage may still be connected to
the cabinet (upstream the contactor)!
• Ensure, before opening the medium voltage doors, that the input medium
voltage lines are disconnected from mains and grounded.
• It is absolutely forbidden to change the position of the internal selector
switches while Line Contactor is closed.
• Before closing the doors for medium voltage operation, ensure that the low
voltage Test Harness is not connected. The Test Harness is only used for
the low voltage test. As a rule, always disconnect the harness immediately
after ending the low voltage test. It should be mounted inside small plastic
bag in the drawing pocket. This Test Harness is equipped with long tape,
intended to prevent forgetting it connected. Never cut this warning tape.
Leave open for its full length and laid in such a way that the harness will
not be forgotten connected after the low voltage test.
• The Line Contactor is not designed for disconnecting high short circuit
currents. Therefore the trip relay terminals 39-40-41 must be used to open
the upstream breaker. Alternatively, upstream fuses can be used.
• The software of the external PLC (if used) controlling the starter must
check the status of the trip relay in customer terminals 39-40-41. Upon
detecting a trip signal, the PLC should open the Remote Start / Stop
contact (connected to customer terminals 15-16) immediately.
10.1 Operational notes
• The seven Logic Inputs of the Control Module (terminals 4-5-6-7-8-9 & 19-20-21) are high impedance
inputs. Add an auxiliary relay for each Logic Input connected through long wire to a remote location
outside the HRVS-DN cabinet.
• Do not connect power factor correction capacitors in parallel with the motor at the output side of the soft
starter. It may cause an immediate damage to the starter and/or capacitors and can be dangerous.
• Do not use power factor capacitors at all if the starter is powered from a generator. The capacitors may
interfere with the voltage regulator of the generator. They may cause significant dangerous over voltages.
• If there are power factor capacitors connected upstream of the starter, and they are mounted close to the
starter, it is recommended to disconnect the capacitors until the end of commissioning.
• Perform a Megger test to the motor and its cables while disconnected from the cabinet. After the end of
test, leave the cable unconnected to enable the low voltage test.

_______________________________________________________________________________________________

94 • Commissioning and Operation Manual
10.3.1 How Does it Operate?
Selector switches position: Local/Remote/Comm./Off selector is in the Local position and DOL/Soft
Start selector switch is in Soft Start position.
Soft start process is initiated when the Start pushbutton (ST terminals 4 & 3) is pressed.
RS relay is energized (RS terminals 2 & 10). RS N.O. contact (RS terminals 9 & 11), connected in parallel with
the start pushbutton (ST terminals 4 & 3) and holds the relay energized.
Line Contactor C1 and interposing relay RC1 are now energized via another N.O. contact of RS (RS terminals
1 & 3).
Start command to the soft starter is initiated after the Line Contactor is closed (C1 terminals 13 & 14) and via
another N.O. contact of RS (RS terminals 6 & 7) to the soft starter by connecting control voltage to terminals 5
& 6 of the Control Module.
FR relay is energized and energizes the firing transformer via its N.O. contact. (FR terminals 1 & 3)
Relay K1 (IMMEDIATE) is energized immediately after start command is initiated to the soft starter.
The starter ramps up the mains voltage to the motor until it reaches full voltage.
Relay K2 (END OF ACCELERATION) is energized after programmable time delay (default of 5 seconds). The
Bypass Contactor C2 is energized through the N.O. contact of K2 (K2 terminals 6 & 7).
FR relay de-energizes after 2 more seconds and disconnects the firing transformer from the control voltage.
Motor is now running with the Bypass Contactor (C2) closed and the soft starter Power Section is idle.
Soft stop process is initiated when the Stop pushbutton (SP terminals 1 & 2) is pressed.
RS relay is de-energized.
Soft Starter terminals 4 & 5 are disconnected (RS terminals 6 & 7) from the control voltage and cause the soft
starter to enter into soft stop process.
FR relay is energized and energizes the firing transformer via its N.O. contact. (FR terminals 1 & 3)
K2 relay is de-energized.
Bypass Contactor C2 de-energizes via the N.O. contacts of K2 (K2 terminals 6 & 7).
The soft starter ramps down the voltage to the motor.
At the end of the soft stop process the HRVS-DN de-energizes K1 relay. N.O. contact of K1 (k1 terminals 6 &
7) relay in series with N.O. contact of RC1 (RC1 terminals 1 & 3) act as a holding system to the Line
Contactor C1. This enables the Line Contactor to be energized until the soft stop process is concluded.
FR relay is de-energized and de-energizes the firing transformer via its N.O. contact. (FR terminals 1 & 3)
Upon Fault condition:
If trip condition, is detected by the HRVS-DN, K3 is energized. FT and FT/1 are de-energized via N.C. contact
of K3 (K3 terminals 5 & 6) causing RS to trip, C1 to trip and L4 (Fault indication lamp) to turn on.
If trip condition is detected by the external motor protection relay, customer terminals 17 & 18 are opened,
causing FT and FT/1 to be de-energized.
Selector switches position: Local/Remote/Comm./Off selector is in the Remote position and DOL/Soft
Start selector switch is in Soft Start position.
The process is exactly the same as above but RS relay is directly controlled by the remote Start/Stop contacts
(Customer terminals 15 & 16).
WARNING!
When operating the HRVS-DN cabinet from Remote or via the communication
links it is extremely important, because of safety reasons, to monitor the Trip
relay (FT/1 terminals 39-40-41)) indication (See Figure 38 page 91).
When the trip relay signals for trip remove the start command!
Selector switches position: Local/Remote/Comm./Off selector is in the Comm. position and DOL/Soft
Start selector switch is in Soft Start position.
When it is required to control the cabinet via communication (not only to monitor and/or change the
parameters) it is required to install, in additional to the communication PCB (either Modbus or Profibus), an
optional Relay PCB.
When the selector is set to communication control, the RS relay is controlled by a relay located in the optional
Relay PCB mounted in the Control Module.
Output terminals from the optional Relay PCB are 31, 32. Refer also to Figure 13 page 29.
_____________________________________________________________________________________________

95 • Commissioning and Operation Manual
Selector switches position: Local/Remote/Comm./Off selector is in the Local or Remote position and
DOL/Soft Start selector switch is in DOL position.
Switch the selector Switch S1 to Bypass position only for testing the cabinet or in rare cases when the HRVS-
DN does not function properly.
When Selector switch S1 is in DOL position, control voltage from terminal 1 of the soft starter is removed thus
the soft starter is not in active. Bypass Contactor C2 is energized.
Start/Stop commands are initiated in the same way as if selector switch S1 is in Soft start.
Notes:
• When selector switch Local/Remote/Comm./Off is in Comm. position and DOL/Soft Start selector switch is in
DOL position it is not possible to control the cabinet.
• When DOL/Soft Start selector switch is in DOL position motor is not protected unless external or internal
protections are installed.
WARNING!
When operating the HRVS-DN cabinet from Remote or via the communication
links it is extremely important, because of safety reasons, to monitor the Trip
relay (FT/1 terminals 39-40-41)) indication (See Figure 38 page 91).
When the trip relay signals for trip remove the start command!

96 • High-Pot Test of the HRVS-DN Cabinet
11. HIGH-POT TEST OF THE HRVS-DN CABINET
Note: The high-pot test is performed in the factory as part of the cabinet FAT. (Factory Acceptance
Test). Thus it is not recommended to do the high-pot test at customer site.
High-pot test levels and duration are as follows:
• Up to 3.6kV: 10kVAC for 60 seconds
• Up to 7.2kV: 20kVAC for 60 seconds
• Up to 12kV: 28kVAC for 60 seconds
• Up to 15kV: 38kVAC for 60 seconds
Two options for high-pot test available:
• With the EPT-Tx connected. In this case only one test can be performed when the soft starter is
short connected as one unit (L1 to U, L2 to V, L3 to W and L1 to L2 to L3)
• With EPT-Tx disconnected. In this case it is possible to perform the high-pot test between each
of the phases while the other two phases are grounded.
11.1 High-Pot Test in HRVS-DN up to 6.6kV, EPT-Tx Connected
Preparations (refer to Figure 39):

102 • Test Procedure for Low Voltage Testing
12. TEST PROCEDURE FOR LOW VOLTAGE TESTING
12.1 Accessories Required for LOW VOLTAGE Testing of the Starter and Cabinet.
Control cable – three wires (two wires+ground) and a switch, to connect the control voltage (110VAC,
230VAC, 115VDC, 125VDC or 220VDC).
Note: Rated power of the control power source should be 2.5kW minimum. This will ensure all inrush
current to the HRVS-DN will not cause voltage drop to the control circuitry.
Power cable - four wires (3 phase + ground) cable + fused three phase switch, to connect the low voltage
400VAC three phase mains voltage to the cabinet. Prepare one side of the cable with a connector to the
mains voltage according to the type of connectors used in the field. The other side with cable lugs or, more
conveniently, with adequate alligator clips suit the bus bar size.
Note: If low voltage mains is generated by a step up or step down transformer, its kVA should be 10 times
greater than the testing motor kVA. Otherwise, the mains (low) voltage may be heavily distorted and
prevent proper operation of the soft starter.
Start / Stop toggle switch with 2 wire cable, to simulate the remote Start / Stop contact.
Three phase 400VAC induction motor 5 -10KW. The motor should be loaded by a fan or any other kind of
inertia (fly wheel).
Digital multimeter.
Test Harness with three colored wires (supplied with the cabinet, located in a small plastic bag in the
drawings pocket).
Note: Test harnesses for other than 400VAC (in the range of 440VAC to 690VAC) can be ordered. The
test voltage (if other than the standard 400V), is indicated on the tape of the test harness.
12.2 Notes and Warnings
Notes:
• The starter and the cabinet are designed to ensure a complete, convenient and safe test procedure for the
starter and for the cabinet, using only the above accessories.
• The next procedure should be used for the following:
o To ensure that the unit functions properly.
o
o
o
To learn the operational modes and options of the cabinet.
To test the cabinet together with the external control system (Factory Scada system, external
PLC, etc.) It is strongly recommended to perform as many tests as possible in the low voltage
mode to debug the external control system hardware and software in this low voltage mode
until the entire system operates satisfactorily.
To debug the system in a rare event of a problem in the starter, cabinet or control system.
WARNING!
• Make sure that Medium voltage is disconnected and secured.
• Check that the test control voltage is equal to the rated control voltage.
• Immediate damage can be expected if the control voltage level is incorrect.
• Check that the three phase mains testing voltage is equal to 400VAC, which is
the standard testing voltage. An immediate damage can be expected if the
mains voltage is not 400VAC±10%.
• Read the soft starter instruction manual carefully as well as the optional Motor
Protection Relay (MPR) instruction manual, If installed.

106 • Test Procedure for Low Voltage Testing
12.3.1 Current Gain Dip Switches Setting
The unit is factory calibrated to the rated current of the starter. For example, if the rated current is 320A then
the rated current of the low voltage motor used for testing would be 6A. The ratio between these current
values is 53. In order to enable testing with that low level of current, additional gain should be added to the
current path. To do so, loosen the four screws holding the display case that covers the upper Printed Circuit
Board (PCB). Slide out the top while the two bottom screws are used as a shaft. On the right side of the
PCB, there are three couples of Gain dip switches. Each pair is for a single phase. Note that all Gain dip
switches are set to ON. Gain dip switch # 1 when set to off (for testing) adds gain of 5. Gain dip switch # 2
when set to off, adds gain of 13.4. By setting both to OFF, a gain of 5x13.4=67 is added. Set the Gain dip
switches according to the ratio between rated starting current and the motor rated current. In the above
example of 320A versus 6A, set both Gain dip switches on each phase to OFF. Refer to Figure 47 below.
12.3.2 Test Harness Installation
Figure 47 – Current Gain Dip Switches Location
Warning: The Standard test harness is designed for testing with low voltage mains, rated 400V.
When the test harness is ordered for higher than 400V, internal resistors are normally connected
in the middle of the wires. Never use the standard 400V Test Harness to perform low voltage tests
with test voltages that exceed 400V . Higher than the specified voltage may cause damage to the
EPT transmitter.
12.3.2.1 Test Harness Installation in HRVS-DN up to 6.6kV
The Test Harness includes three colored wires: blue, red and green wires.
These wires are used to change the resistors voltage dividing ratio in the EPT-Tx (Electronic Potential
Transformer Transmitter).
At one end of each colored wire there is banana plug with the same color as of the wire.
At the second end of the blue wire there is an alligator clip.
The second end of the red and green wires are clamped together and connected to a second alligator clip.
On the front side of the EPT-Tx you will see three colored round stickers: blue, red and green stickers.
On the rear side of the EPT-Tx, exactly at same location as the stickers, there are three small holes. These
holes have an internal banana jacks for the banana plugs.
Connect the three banana plugs the banana jacks at the rear side of the EPT-Tx. Ensure that the wire colors
match the round sticker colors at the front of the EPT-Tx.
Connect the alligator clip marked “1”, with red and green wires to phase L1.
Connect the alligator clip marked “3”, with blue wire to phase L3.

10. It is strongly recommended that another person stand near the motor and have cellular (or other)
contact with you. He should be authorized to stop immediately (if a remote stop button is
available) or to ask you to immediately stop in any case where an unusual mechanical noise is
heard.
11. During the entire starting time you should continuously read the three currents as shown on the
starter’s display. They should show, more or less same values.
12. If the currents are significantly different - STOP IMMEDIATELY. Do not wait the total start time
until a trip occurs.
13. In any problem occurs, look at the following troubleshooting instructions.
14. It is strongly recommended to go back to the low voltage test if in doubt.
15. After successful starting, with real load, set MAX START TIME (in START PARAMETERS
page) to few seconds above the actual time seen in the STATISTICAL DATA page, to prevent
starter and motor overheating if load is increased and motor cannot start.

• Check LAST START PERIOD and set MAX. START TIME to approximately 5 seconds
longer than the LAST START PERIOD.
• For future reference it is advised to keep records of the following parameters in the
STATISTICAL DATA:
LAST START PERIOD
LAST START MAX I
13.5 Examples of Starting Curves
13.5.1 Light Loads - Pumps, Etc.
(In these cases the actual current is always lower than the CURRENT LIMIT setting)
INITIAL VOLTAGE- set to 30%
CURRENT LIMIT - set to 300-350%
ACCELERATION TIME- set to 10 sec.
Upon start, the voltage quickly increases to the INITIAL VOLTAGE value (30% of Un) and then gradually
ramps-up to nominal.
The current will simultaneously increase to peak current value (lower than the CURRENT LIMIT setting),
before smoothly decreasing to the operating current.
13.5.2 High Inertia Loads: Crushers, Centrifuges, Mixers, Etc.
(In these cases the actual current is at the CURRENT LIMIT setting during part of the starting time)
INITIAL VOLTAGE– set 40%
CURRENT LIMIT– set 400%
ACCELERATION TIME– set 3 sec
_______________________________________________________________________________________________

112 • Start Procedure for Medium voltage Motor
Upon START the voltage and current increase until the current reaches the CURRENT LIMIT value. The
voltage remains at this value until the motor reaches close to nominal speed, where current starts to decrease
and voltage continues to ramp-up to nominal.
13.5.3 Special Starting Using DUAL ADJUSTMENT
Using two starting characteristics, the HRVS-DN will accelerate using standard characteristics (INITIAL
VOLTAGE, ACCELERATION TIME and CURRENT LIMIT). After transition (tx) (IMMEDIATE relay delay),
voltage to input terminal 8 is switched on using the DUAL ADJUSTMENT characteristic to complete
acceleration.
Perform the following steps:
• To use DUAL ADJUSTMENT automatically, connect IMMEDIATE in series to input terminal 8 as shown in
section 13.5.3.1 below.
• Program IMMEDIATE/SHEAR-PIN relay to IMMEDIATE (default setting) and program RELAY ON DELAY to
tx.
• Program PROG. INPUT #8 to DUAL ADJUSTMENT (default setting).
• Program standard parameters and DUAL ADJUSTMENT parameters as shown in the table below.
Using two starting characteristics, the HRVS-DN will accelerate to reach the 200% current limit. After tx
voltage to PROG. INPUT #8 is switched on, using the DUAL ADJUSTMENT characteristic to complete
acceleration.

113 • Start Procedure for Medium voltage Motor
13.5.3.1 Special Starting – Using DUAL ADJUSTMENT – Wiring Diagram
13.5.4 Choosing a Suitable Pump Curve (Centrifugal Pumps)
13.5.4.1 Starting Curve
• Adjust MAIN PARAMETERS as necessary (FLA, FLC, etc.).
• Set STARTING CURVE, ACCELERATION TIME, CURRENT LIMIT, and INITIAL VOLTAGE to their default
values (curve 1, 10 sec., 400% and 30% respectively).
• Start the pump while watching the pressure gauge as the pump starts and look for overshooting (“pressure
surge”) of the gauge needle above the target pressure. In case of over pressure, choose a peak torque
reduction curve (SOFT START CURVE 2!!).
• Set SOFT START CURVE 2!!, increase ACCELERATION TIME to 15 seconds and reduce CURRENT LIMIT
to 350%. Start the pump and watch the pressure gauge while the pump starts.
• In most cases, overshooting is reduced. If the overshoot persists, increase ACCELERATION TIME to 25
seconds (confirm with motor manufacturer) and try again.
• If the overpressure persists, increase the SOFT START CURVE setting to 3!!, or 4!!, if necessary. Each
increase in the SOFT START CURVE setting will reduce the peak torque, thus reducing the overpressure
and preventing “pressure surge” during start.
13.5.4.2 Stopping Curve
• Adjust MAIN PARAMETERS as necessary (FLA, FLC, etc.)
• Set SOFT STOP CURVE and DECELERATION TIME, to their default values (curve 1, 10 sec.,
respectively).
• Stop the pump, watching the pressure gauge and check valve as the pump stops. Look for overshooting
(“water hammer”) of the gauge (abruptly stops the pump and the motor).
_______________________________________________________________________________________________

114 • Start Procedure for Medium voltage Motor
• Select SOFT STOP CURVE 2!! and increase DECELERATION TIME to 15 seconds. Stop the pump and
watch the pressure gauge and the rate of closing of the check valve as the pump stops. Abrupt stopping of
the pump and motor will cause a loud audible noise emitted from the check valve.
• In most cases, “water hammer” is reduced. If “water hammer” persists, increase the time to 25 seconds
(confirm with motor manufacturer) and try again.
• If “water hammer” persists, increase the SOFT STOP CURVE setting to 3!!, or 4!!. Each increase in the
SOFT STOP CURVE will reduce the abrupt stop of the pump, thus preventing the “water hammer”
phenomenon.
13.5.4.3 FINAL TORQUE During Soft-Stopping a Pump Motor
While decelerating, the check valve may close before DECELERATION TIME has elapsed, thus allowing
current to flow through stator winding causing unnecessary heat. Select FINAL TORQUE sensitivity to 1 and
stop the pump, then confirm that the current stopped flowing through the motor shortly after the check valve
closed.
If current still flows more than 3-5 seconds after check valve closure, increase FINAL TORQUE (up to a
maximum value of 10) to stop current flow earlier.
13.6 How to set MPS-3000 and DPM-10 when installed with HRVS-DN
If MPS-3000 (Solcon motor protection) and/or DPM-10 (Solcon digital power meter) are integrated in the
HRVS-DN cabinet in a way that voltage readings are from the EPT and current measurements are from the
HRVS-DN internal CTs special attention must be given to the setting of these units.
Before setting the MPS-3000, read the MPS-3000 instruction manual.
Before setting the DPM-10, read the DPM-10 instruction manual.
If the MPS and DPM-10 use separate (not the internal soft starter) CTs and PTs (current and voltage
transformers), then set all MPS and DPM-10 parameters according to the instruction manual.
If, however the MPS and DPM-10 use the HRVS-DN Internal CTs and Electronic Potential Transformer (EPT),
a number of parameter settings must be performed as explained below.
Inside the soft starter, there is an EPT. Its “primary” rated voltage is equal to the starter rated voltage. Its
“secondary” rated voltage is 120VAC.
Inside the soft starter, special CTs are used. Their primary rated current equals to the starter rated current.
Their secondary rated current is 2A. The secondary current is connected to the MPS-3000 5A input and to the
DPM-10 5A input.
_____________________________________________________________________________________________

In the MPS-3000 SYSTEM PARAMETER setting page, please set:
115 • Start Procedure for Medium voltage Motor
LINE VOLTS
VT PRIMARY
VT SECONDARY
MOTOR FLC
CT PRIMARY
GND CT PRIMARY
= Actual rated line voltage (should be equal or lower than starter rated voltage).
= Starter rated voltage (the Electronic Potential Transformer is calibrated to
the starter rated voltage).
= 120 (the EPT “secondary” rated voltage).
= Actual Motor Name Plate (Rated) current (should be equal or lower than
starter rated current).
= 2.5 x Starter Rated Current. (See note 1 below)
= same as CT PRIMARY setting.
In the DPM-10 PARAMETER setting page, please set:
P+ (Potential Transformer ratio) = Ratio between Primary and secondary of the P/T. Set to: Vn/120.
If, for example Vn=3300V then set to: 3300/120=27.5.
C+ (C.Ts Primary) = 2.5 x Starter Rated Current.
Explanation of CT PRIMARY: If The rated starter current is - for example - 1000A, its CTs (that are used
also for the MPS and DPM-10) are 1000 / 2A.
Please note that CTs secondary current is 2A, not 5A as of the DPM-10 and as of the MPS-3000 (See note 1
below).
When 1000A flows, the DPM-10 and MPS-3000 gets only 2A instead 5A and will calculate 2 / 5 x1000 = 400A.
Therefore we have to set the CT Primary to 1000x(5/2)=2500, which with 2A will read exactly 1000A as
required.
Notes:
1. In the MPS-3000 there is a second set of current transformers with a secondary of 1A. (Terminals 82,
85, 88 and 91).
In this case, when 1000A flows, the MPS-3000 gets 2A instead 1A and will calculate 2 / 1 x1000 = 2000A.
Therefore we have to set the CT Primary to 1000x(1/2)= 500, which with 2A will read exactly 1000A as
required.
2. In the MPS-3000 and DPM-10, each parameter has to be stored separately (while in the soft starter
you store all parameters of a page together).
_______________________________________________________________________________________________

116 • Trouble Shooting
14. TROUBLE SHOOTING
The following procedures should be done only upon fault and in case trouble shooting is required.
14.1 In-Out Resistance and Cathode-Cathode Resistance
Verify that the motor is disconnected.
Disconnect the cabinet mains isolator switch or fuses, if installed.
In-Out resistances should be the same for all three phases in each model. Cathode-Cathode
resistances are indicated in the following table:
HRVS-DN Rated
Voltage
L1 – U
L2 - V
L3 - W
Cathode-Cathode
2.3kV 1.2MΩ ±10% 1/2 of In-Out resistance
3.3kV 135kΩ ±10%
1/3 of In-Out resistance
4.16kV 135kΩ ±10%
6.6kV 300kΩ ±10%
10kV 420kΩ ±10%
11kV 450kΩ ±10%
13.2kV 500kΩ ±10%
13.8kV 500kΩ ±10%
15kV 550kΩ ±10%
1/5 or 1/6 of In-Out
resistance. (depends
on number of thyristors
in the soft starter)
Refer to Figure 50 In order to identify the Cathode terminals of all 6 SCRs on the firing PCB.
A number is written on the firing PCB to identify the SCRs.
Measure Cathode-Cathode resistances as follows:
Cathode SCR#1 to Cathode SCR#4
Cathode SCR#2 to Cathode SCR#5
Cathode SCR#3 to Cathode SCR#6
Verify that values correspond to the above table.
14.2 Rgk (thyristors Gate-Cathode) Resistances.
Thyristors Gate-Cathode resistances can easily be measured from the firing PCBs.
In order to access the testing points the front cover of the Power Section needs to be dismantled.
Gate-Cathode connection points of SCR#1 are illustrated in Figure 50. Measure all SCRs’ Rgk
resistances in each of the phases.
Rgk values should be about the same for all thyristors in the phase, and in the range of 7-20 Ω.
Figure 50 – Firing PCB – SCR#1 Gate-Cathode Testing
_____________________________________________________________________________________________

14.3 Firing Test
The purpose of this test is to check that the firing system of all thyristors functions properly.
This procedure requires control supply voltage only (No need for mains three phases).
• Disconnect mains. Verify all safety issues are
resolved.
• Open 10 hexagon head white plastic screws
holding the front cover of all 3 phases.
• Dismantle front cover of all three phases
117 • Trouble Shooting
• Identify 6 green LEDs and 6 red LEDs as

Note:
• The firing test is limited to 30 seconds. If you did not manage to conclude the test you can repeat until all 5
stages are done.
If the firing test fails:
• Check the fuses in the switch mode power supplies (PC2075 for AC control voltage, PC2076 for DC control
voltage). Refer to section 10.2.4 page 89 for fuse locations.
Note: DC control voltage uses all three fuses in a series, so if one fails to operate, all firing LEDs can’t light.
• Check that fiber optic wires # 1, 3 and 5 (firing phases 1, 2 and 3) are properly connected according to the
markings on the Control Module.
• Check that they are inserted into their connectors to the full depth and not damaged .
• Check that the fiber optic wires of the power modules that are connected between the individual power
supplies (PC2075 or PC2076) and the firing PCBs are properly inserted.
• When Control Voltage is turned ON, the green LEDs in the power modules may blink shortly. This is normal.

What To Do
• Verify that all three mains phases are connected.
• At low voltage, testing a missing phase can cause UNDER/NO VOLTAGE
trip.
• Verify that the test harness is connected to the EPT-Tx while testing at low
voltage.
• Verify that the Line Contactor is closed, at least for a short time, at the
beginning of the start process.
• If external line (mains) contactor is used, ensure that its auxiliary contact is
wired back to the HRVS-DN cabinet and used (in series with RS relay
contact) to initiate the start command (this contact should not be bridged in
the customer terminals).
• Check UNDERVOLT. TRIP setting level in MAIN & PROTECT page.
• Verify that the Electronic Potential Transformer Receiver (EPT-Rx) fuse
located in the Receiver auxiliary supply plug is OK.
• Verify that the fiber optics wires connecting the EPT-Tx and EPT-Rx are
properly connected.
• Move the external mains connection from upstream of the Line Contactor to
down stream the Line Contactor and turn on the mains voltage . Check
120VAC line to line between EPT-Rx output terminals. Try to start now.
• Take out fibers 11 and 13 from the EPT-Rx, they should emit red light with
the same intensity.
• Check that the 15 pin white connector is properly connected, at the back of
the Control Module.
• Make sure that the mains testing voltage is 400V or as written as on the test
harness.
• If it is higher, disconnect the mains voltage immediately.
• Check OVERVOLT. TRIP setting level in MAIN & PROTECT page.
• Phase sequence of the mains lines is wrong.
• Two options are available:
o Swap two input lines.
o Set PHASE SEQUENCE setting in FAULT PARAMETERS as
required.
• The default setting allows for one start per 20 minutes.
• To reset the fault find the NUMBER OF STARTS setting at the end of the
START PARAMETERS page, increase setting to OFF, then reset. Store at
the end of the page.
• Be sure to set for medium voltage operation after end of testing.
• Verify that the motor’s rated current multiplied by the Gain (as set by the dip
switches) is greater than or equal to 30% of FLC.
• It may occur when the load is not a motor.
• Verify that fiber optic wires 1,3 & 5 are properly connected.
• Verify that Current Gain dip switches are set equally for the three phases and
according to the ratio between starter rated current and testing motor rated
current.
• Try to start using SOFT START CURVE 0, the basic curve. If the motor is not
loaded and has no inertia, the motor may vibrate after reaching full speed.
This is normal and will not occur with the MV motor.
o If the test motor starts properly then the current transformers and their
wiring should be checked.
o If the test motor does not start properly the measured current may be
too low.
• Perform a firing test as described on section 14.3 page 117.
• Check fuses and fuses holders in phases firing power supplies. Refer to
section 10.2.4 page 89.
• Sometimes SOFT START CURVE 0 enables the soft start process, even if a
CT or its wiring is problematic, if mains conditions are not ideal or with nonstandard
motor. Current in every phase must, however be above 5% of
starter FLC, or the same trip might occur.

What To Do
• Check that pairs of Gain dip switches are set identically for the three phases.
• Try SOFT START CURVE 0.
• Verify that the motor is not too small. Try to use a larger motor, with inertia or
loaded, if possible.
• If vibration occurs at the beginning of start process with SOFT START
CURVE 1, 2, 3, 4 or 5 try SOFT START CURVE 0.
• If vibrations occurs at the beginning of start process with SOFT START
CURVE 0 check low voltage test harness installation, fiber optic 11 & 13 and
EPT-Rx outputs.
• Vibrations, when approaching full speed at the start of SOFT START CURVE
0 with motors that have no load are normal and do not indicate a problem.
With other SOFT START CURVE it can occur with small / unloaded motor
which accelerates too fast. Try to reduce INITIAL VOLTAGE to a minimum.
• Verify that current Gain dip switches are set according to the ratio between
the rated current of the HRVS-DN and the testing motor rated current .
• If the test motor is loaded or has some inertia, try to start with SOFT START
CURVE 0, the basic curve. If the problem is solved, then test the current
transformers and their wiring. Sometimes the SOFT START CURVE 0
enables a loaded motor to start properly, even if a CT or its wiring are faulty
or with a problematic mains (weak transformer for the low voltage test).
• Check that all fibers are properly connected according to their numbers.
• Verify that Current Gain dip switches are set according to the ratio between
the rated current of the starter and the testing motor rated current.
• The trip can occur if added (by setting of Gain dip switches) gain is too high.
• Try to start with SOFT START CURVE 0 and stop with SOFT STOP CURVE
0. If problem us solved the current transformers and their wiring should be
checked.
• Check that all fiber optic wires are properly connected.
• Verify that all three phases are within range.
• Verify that EPT-Tx and EPT-Rx fiber optic wires are properly connected.
• If low voltage mains is powered from a generator, check that frequency is

• Use standard curve SOFT START CURVE 1 and SOFT STOP CURVE 1.
• Verify that Current Gain dip switches are set according to the ratio between
the rated current of the starter and the testing motor rated current.
• Check Bypass Contactor wiring.
• Verify that HRVS-DN FLC setting parameter is set according to the rated
current of the starter.
• Current Gain dip switches gain current reading as follows:
o Both Gain dip switches of phases set to on -> gain = 1
o Gain dip switches # 1 of phases set to off -> gain = 5
o Gain dip switches # 2 of phases set to off -> gain = 13.4
o Both Gain dip switches of phases set to off -> gain = 67
• Use a Clamp-on the Ammeter to measure test the motor current.
• Starter’s current reading should be approximately actual current multiplied by
the gain ratio set by the Gain dip switches.
• Set parameters to default parameters and re-program the HRVS-DN.
• Verify that current Gain dip switches are set according to the testing motor
rated current versus rated current of the starter. Overload trip can occur if
gain (set by Gain dip switches settings) is too high.
• Verify that the HRVS-DN FLC setting parameter is set according to the rated
current of the HRVS-DN.
• Set Motor FLA identically to HRVS-DN FLC.
• Reset, start again and read currents on screen.
• Check if current readings after start are is more than starter’s rated current.
• Reduce setting of Undercurrent setting in the MAIN & PROTECT Parameters
settings.
• This is normal. The MPR (Motor Protection Relay) does not have extra gain
for testing. Its current reading may be very low, below the minimum
threshold.
• Might occur when the Local / Remote switch is set to remote, and the remote
contact is closed.
Note: It is the responsibility of the remote controller to open the remote

• Verify that the Mains voltage is connected (no open Isolator, etc.).
• Verify by listening, that the Line Contactor is closed at start, at least for a
short period of time (until the Trip command opens it).
• If an external Line Contactor is used, ensure that its auxiliary contact is wired
back to the HRVS-DN cabinet and used (in series with RS relay) to apply the
start command in terminals 5 & 6 in the Control Module (this contact should
not be bridged in the customer terminals.
• Check UNDERVOLT TRIP setting level in the MAIN & PROTECT setting
page.
• Verify that the fuse located in the EPT-Rx connector did not melt. Refer to
section 10.2.4 page 89.
• Check that the 15 pin white connector is properly connected, at the back of
the HRVS-DN Control Module
• Disconnect and secure the mains source.
• Check EPT-Tx to EPT-Rx fiber optic connections.
• If required perform a second low voltage test .
• Verify that HRVS-DN rated voltage is identical to mains voltage.
• Check OVERVOLT TRIP setting level in MAIN & PROTECT page.
• If the unit is powered from the generator, check its output voltage.
• Phase sequence of the mains lines is wrong.
• Two options are available:
o Swap two input lines.
o Set PHASE SEQUENCE setting in FAULT PARAMETERS as
required.
• Check and verify correct settings of the following parameters in the START
PARAMETRS page: NUMBER OF STARTS, STARTS PERIOD and START
INHIBIT. Refer to section 7.8.3 page 60.
• Warning: Wait at least the required time between starts to prevent damage,
both to the starter and motor !
• Verify that the Current Gain dip switches are set to ON.
• Disconnect medium voltage and verify that motor and mains input are
properly connected.
• Check that all fiber optic wires are properly connected.
• Set SOFT START CURVE 0 and try to start.
o If the problem is solved and the start process is OK, leave it on SOFT
START CURVE 0. Set SOFT STOP CURVE 0 as well.
o If the problem is not solved then the measured current in one or more
phases may be too low.
• Another reason can be nonstandard motor parameters.
• SOFT STOP CURVE 0 may enable it to function properly, even if the mains
conditions are not ideal or with non-standard motor. Current in every phase
must however be above 10% of starter FLC, or the same trip may occur.
• Mains and system conditions are not optimal for other than SOFT START 0
and SOFT STOP CURVE 0. Set both parameters in START PARAMETERS
page and in STOP PARAMETERS page.
• Try to start the motor again.
• Check that all fiber optic wires are properly connected.
• Try to start with SOFT START CURVE 0.
• If the problem is resolved, check the current transformers and their wiring.
• SOFT START CURVE 0 may enable it to function properly even if a CT or its
wiring are faulty.
• Verify that current Gain dip switches are set to on and not left in the
high gain off position, used for the low voltage test.
• Try to start and stop with SOFT START 0 and SOFT STOP CURVE 0.
• If the problem is solved, check the current transformers and their
wiring.
• Check that all fiber optic wires are properly connected.

127 • HRVS-DN Communication (ModBus Protocol)
16. HRVS-DN COMMUNICATION (MODBUS PROTOCOL)
16.1 Introduction
This document summarizes the Modbus serial link protocol to / from the Digital Soft Starter (HRVS-DN). The
HRVS-DN can be equipped with many other serial link protocols.
Features:
* RS485 Hardware.
* Asynchronous serial link.
* Half duplex.
* Format: Modbus RTU Mode (Remote Terminal Unit Mode).
- Binary,
- Each character contains 11 bits:
- 1 start bit
- 8 data bits, least significant bit sent first.
- 1 Parity bit. Even / Odd / No can be selected.
- 1 Stop bit if Parity is used, 2 stop bits if Parity is not used.
- Cyclical Redundancy Check (CRC), 16 bits.
* Baud Rates: 1200 / 2400 / 4800 / 9600 bits per second.
* Response time of the HRVS-DN:
- Normally, 4ms

128 • HRVS-DN Communication (ModBus Protocol)
16.2 Basic Structure of the Serial Link Frame
The Modbus RTU frame has the same principal structure for both the "Query" transmission from the Master to
the Slave (HRVS-DN) and the Response transmission from the Slave to the Master:
"sync": Silent Interval for at least 3.5 character times 1
byte 1: Serial Link No. (= Slave Address) (1..247)
byte 2: Function (1,2,3,4,5,6,8,15 &16 are supported)
byte 3: Data Bytes ($XX)
. . ($XX)
. . ($XX)
byte n-1: CRC_Low
($XX)
byte n : CRC_High
($XX)
"sync": Silent Interval for at least 3.5 characters
16.3 SYNC (Silent Interval)
In RTU mode, messages use a "Silent Interval" more than 3.5 characters to "synchronize". This silent interval
separates transmission frames.
The entire frame must be transmitted as a continuous stream. A silent interval of more than 3.5 characters
during frame transmission will cause the receiving device to ignore the incomplete frame. The next byte is
assumed to be the Serial Link No. of the next frame.
Ignoring the frame can also occur if a second message is transmitted less than 3.5 characters from the end of
the previous frame. This causes the receiving device to consider that frame to be a continuation of the first
frame, thus resulting in a CRC error.
16.4 Serial Link No. (Slave Address)
Contains HRVS-DN Slave Number (1..247) on the serial link. The HRVS-DN default value is 248, which is the
communication OFF condition. Serial Link No. is used as the first byte in both the "Query" transmission from
Master to Slave and in Response transmission from Slave to Master.
Note: Address 0, which is normally used for broadcast transmissions is not supported by the HRVS-DN.
16.5 Function
The Function code informs the HRVS-DN what action is requested. In most cases, Function is used as the
second byte in both the "Query" transmission from Master to Slave and in Response transmission from Slave
to Master.

16.6 List of Functions Supported By The HRVSDN
Function Modbus Name
Use in HRVS-DN
01 Read Coil Status Read discrete commands status.
02 Read Input Status Read discrete inputs status.
03 Read Holding Registers. Read parameter settings.
Read actual data (for Modbus Plus users).
04 Read Input Registers. Read actual data.
05 Force Single Coil. Force one discrete command.
06 Preset Single Register. Write one parameter setting.
08 Diagnostics. Loopback diagnostics.
15 Force Multiple Coils. Force discrete commands.
16 Force Multiple Registers Write parameter setting
control commands
DATA
Data field includes information transferred to and from the HRVS-DN. The specific data format is changed with
Function. When Word data parameters are transmitted, High Byte is transmitted first, followed by the Low
Byte.
CRC
The CRC (Cyclic Redundancy Check) two bytes (16 bit) are used to check the bytes of the entire frame.
It is generated in the master device and transmitted as the last two bytes of the frame (Low byte is appended
first, followed by the High byte). The slave device regenerates the CRC bytes and compares it to the CRC
bytes received. If the CRC bytes are not identical, the frame is flushed and no response is transmitted to the
master.
HRVS-DN MEMORY ORGANIZATION
The HRVS-DN memory is organized according to the common Modbus addresses as follows:
_______________________________________________________________________________________________

130 • HRVS-DN Communication (ModBus Protocol)

Notes:
1. Actual Data parameters can be read both at 3X references starting at parameter #1, or (same parameters)
at 4X references starting at parameter #257 (100 hex higher). The additional mapping in 4X references is
designed for the convenience of Modbus Plus users.
2. HRVS_DN can be controlled using the standard discrete commands (Coils, 0x references) or by writing to
parameter setting #753 with function 16. The additional control option using 4X references is designed for
the convenience of Modbus Plus users. To control, write to register #753 (address 752) only! (one register
write, with function 16).
3. Function 3 should be used to read 4X references. Function 4, to read 3x references.

16.8 Parameter Settings (4X References)
Parameter settings include all parameters that can be set manually. These parameters determine the modes
of operation of the HRVS-DN. They also set protections level. All parameters are word (two bytes)
parameters. The protocol supports both reading and modifying of (most of) these parameters.
Note: Use function 3 to read the setting parameters.
Any one of these parameters must be set with care. Inappropriate settings of some parameters can
result in damage to both the motor and the HRVSDN.

Notes:
1. Parameter # is "1 based". The address is 1 lower than parameter #. For example address of parameter #1
is 0 (40000).
2. When the Preset Single Register Function (06) is used to adjust one parameter setting, the
communication program checks that the parameter value is within the allowed limits. If not, an Exception
Response (Exception code 03) is returned instead of Normal response. See Exception Responses later in
this document.
3. If Preset Multiple Register Function (16) is used to adjust one or multiple parameter settings, then even if
one or more parameter settings are out of range, Normal response will be returned.
HRVS-DN program will check later the value of each parameter. If it is beyond the allowed limit, the limit
value will be stored instead of the transmitted parameter value.
4. It is strongly recommended to preset parameter settings only when the motor is stopped. The HRVS-DN
enables, however to preset one parameter (using function 06 only) when the motor is running with closed
Bypass Contactor. When motor is Soft Started, Soft Stopped, runs with open bypass or at slow speed, the
HRVS-DN ignores "Preset Single Register" or "Force Multiple Register" instructions. A "busy" Exception
response is returned by the HRVS-DN whenever its logic condition does not enable presetting.
5. Always wait more than 0.5Sec after using Functions 06 or 16 to preset parameter(s) before transmitting
again to the same HRVS-DN.
6. Communication parameters 81, 82, 83 can only be read through the serial link. They can only be set
(written) manually.
7. It is the user’s responsibility to read and check all changed parameter settings after presetting.
8. It is not possible to write data to the setting parameters when dip switch 8 (pc2000) is set.

2. Bytes 2..8 of the control frame must be exactly as in the following example. Otherwise, an error
message is returned.
3. Hardwired Stop and Soft Stop inputs, overrides the communication. To enable motor starting
through communication, terminal 4 (Stop) must be connected to the control voltage. Connect
terminals 5 & 6 to control voltage through the HRVS-DN Start/Stop optional relay output
contact.
4. Start/Stop and Dual Adj bits, should be of maintained type, like a toggle switch.
5. Reset bit should be of momentary type, like a momentary reset pushbutton. It is rejected, if
given together with Start command.
6. Before (or simultaneously with) resetting, be sure to turn off start/stop relay bit first.
7. It is the host responsibility, to immediately write a Stop command (writing 5A00 Hex) when
detecting that the Trip bit is set in the Logic Status parameter (parameter # 1 on the In data).
This is to prevent unwanted start command upon resetting the fault.

16.13 Exception Responses
When the master sends a query frame to an HRVS-DN, one of the following four responses from the HRVS-
DN is possible:
1. When no communication error is detected in the query, and no mistake is found by the communication
program module in the HRVS-DN, a normal response is returned.
2. If the HRVS-DN does not receive the query frame (for example because of disconnected serial link cable)
then no response is returned by the HRVS-DN. After proper time the master will cause a timeout condition.
3. If the HRVS-DN receives the query, but faulty CRC bytes and / or Parity bits are detected, no response is
returned by the HRVS-DN. After the proper time the master will cause a timeout condition.
4. If no communication error is detected in the query, but the HRVS-DN communication program module
finds an error such as illegal Function, data address or data value, or if the HRVS-DN is busy, then an
Exception response is returned. The Exception response includes Exception Code to inform the master
about the type of the error.
Exception Code Response Frame:
The Exception response frame holds fix number of 5 bytes. The first one, the Slave Address field is the Serial
link number (transmitted in query and identical to HRVS-DN Serial Link No.). The second byte, the Function
field returns the echo of the transmitted query function, but with the Most Significant Bit set to 1 (adding $80 to
the transmitted function code). The third byte is the Exception Code informing about the type of error. The last
two bytes are the CRC bytes.
Exception Codes supported by the HRVS-DN:
Exception Code Type Comment
01 Illegal Function Requested Function is not supported.
Functions 1..6, 8, 15 or 16 are supported.
02 Illegal Data Address Data address is not allowable.
03 Illegal Data Value Data Value is not in allowable range.
06 HRVS-DN Busy HRVS-DN is busy now. The master retransmits the message
later.
Note: After using function 16 to store setting parameters, it is
forbidden to transmit again to the same MPR after less than
1Sec.

Each pair of bytes represents one register; all of the registers are 16 bit numbers.
The first byte represents the high value of the number (the MSB).
17.3.3 Choosing the Receiving DPV0 Registers
There are two methods to change which registers will be displayed in DPV0 (cyclic).
• Change the parameters in the GSD file. This method can be used with both DPV0 and DPV1. The change
can only take place when communication is first established.
_____________________________________________________________________________________________

147 • HRVS-DN Communication (Profibus protocol)
• Write a data request. This method can only be used with DPV1. The change can be made after
communication has already been established.
17.3.3.1 Selection of the DPV0 Registers by the GSD
The GSD file contains a list of parameters at lines 190 to 288.
The parameters appear in blocks, each block contains 4 lines, and each block refers to one register (there are
20 blocks representing 20 registers).
190: ExtUserPrmData = 1001 "INDIREC PAR 1"

Code 2 – GSD file, the part that is responsible for displaying the registers in DPV0 (cyclic)
The second line of each block begins with “Unsigned16”, followed by the register number (shown above in
green).
The list of register numbers appears in section Error! Reference source not found. on page Error!
Bookmark not defined..
17.3.3.2 Selection of the DPV0 Registers through Data Request (DPV1)
By writing to Slot number 1 and Index 2, you can change the register that appears in DPV0.
Remember that for each register there are 16 bits (two bytes/one word). The first byte represents the high
value of the register number.
To demonstrate this, let’s say that we want to see the following registers in DPV0 (cyclic):
1. Logic Status.
2. I1.
3. I2.
4. I3.
5. Voltage.
6. Ctrl-In.
7. Ctrl_Out (relays).
8. Power.
9. Power Factor.
10. Frequency.
_______________________________________________________________________________________________

148 • HRVS-DN Communication (Profibus protocol)
Step 1: Find the register numbers
In this document, we will use a simple PROFIBUS master tool to demonstrate how to change parameters.
This tool is very simple and it allows you to modify the parameters only by writing the hex numbers.
Go to the table in section Error! Reference source not found. and find the register number for each register.
The tool used in our example requires the hexadecimal value so we also need to convert the register number
into its hex equivalent.
The following table shows the register numbers for the registers used in our example.
Register name Decimal number Hex number
Logic Status 1 00 01
I1 5 00 02
I2 6 00 05
I3 7 00 07
Voltage 4 00 04
Ctrl-In 2 00 02
Ctrl_Out (relays) 3 00 03
Power 15 00 0F
Power Factor 17 00 11
Frequency 8 00 08
Step 2: Update the register numbers
In the Data Request area defines the following:
• Slot Number = 1
• Index = 2
• Operation = Write
• Write Data (hex) = the hex numbers in the table above
This updates the registers that are shown in DPV0.

17.3.3.3 Reading of the DPV0 (Cyclic) Registers via Data Request (DPV1)
In the Data Request areas define the following:
• Slot Number = 1
• Index = 2
• Operation = Read
The registers in DPV0 will display in the Read Data (hex) field.

17.4 Operations that are Available in DPV1
• Choose the registers that will display in DPV0 (cyclic). This was described in the previous section.
• Read and write from random registers.
17.4.1 Read and Write from Random Registers via Data Request
Reading or writing by Data Request (DPV1) allows you to read or write up to 20 registers in a single request.
In order to read or write via Data Request (DPV1) you need to perform 2 operations:
• First update the first register number that we want to read or write.
• Second read or write the register.
To configure the first register number, define the following:
• Slot Number = 1
• Index = 2
• Operation = Write
• Write Data (hex) = the first register number
The length of the register number must always contain two bytes (word). If we want to read from register
number 5 we need to read from register number 0x0005. The first byte is the high part of the number (the
MSB).
To read or write multiple registers, we need to define the number of the words that we want to read or write.
The following example shows how to read from register number 0x80 to register number 0x83.
Step 1: Write the number 80 hex to Slot number 2 and Index number 2.

Slot: 2
Index: 2
